Except there isn’t a true “free market” and QF distort the system with cadets. Experience and qualifications have nothing to do with it when someone with no actual flying experience gets a 6 figure job ahead of people who do.
The other contentious issue in aviation is the ability to generate revenue. This is what really killed the regionals in the US. The pay was so low they couldn’t get anyone but the same time there wasn’t a lot of margin to pay more because the planes really don’t generate enough revenue. Then you get to the point where routes might as well go back to the mainline because they have the ability to fly the route putting yourself out of business.
This is the point where this whole outsourcing model implodes as there is a line out the door for mainline yet the regionals can’t pay enough to crew their flights.
